Design goal

The design goal was an infloor heating & domestic hot water (DHW) system, supplied with primarily solar and a high-efficiency gas boiler as backup.

Installation description

The installation was a new house construction - all of the mechanical components (689-gallon insulated stainless steel solar buffer tank, 53-gallon indirect water heater, high-eff wall hung boiler, Caleffi distribution manifold, pumps, calves, piping & controls) needed to fit in an 8' x 8' space and allow for easy access for future service.

System performance

Less than 250 gallons of propane usage in past 12 months says as much about the tight construction as it does with the efficient design of the heating equipment.
